We Service Corte Madera!

Corte Madera’s location along the San Francisco Bay and its varied terrain create unique challenges for homeowners when it comes to foundation stability. Many homes near the waterfront are built on soft bay fill, which is prone to settling and soil liquefaction during seismic events. In hillside neighborhoods, expansive soils and steep slopes can lead to foundation settling, cracks, and structural instability over time.

The city’s proximity to the San Andreas and Rodgers Creek Faults poses a significant seismic risk, making earthquake preparedness a priority for homeowners. Many older homes in Corte Madera were built before modern seismic codes and may lack proper reinforcements. Seismic retrofitting, such as foundation bolting, cripple wall bracing, and shear wall installation, is essential to protect these homes from potential seismic damage.

Drainage issues are also common in Corte Madera, especially during heavy rains when water can pool around foundations or cause hillside erosion. Without proper drainage systems, such as French drains and sump pumps, hydrostatic pressure can build up against foundation walls, leading to cracks and water intrusion. Implementing effective drainage solutions is crucial to safeguard the structural integrity of Corte Madera homes.
